Hello, I found an older thread here while looking for a place to start troubleshooting my step problem and found a thread talking about the very same Eagle model I have. 94' American Eagle here too! But it's an old thread and I cannot reply to it.
The step problem I'm having is slightly different though, as it extends and retracts just fine, normally as it should, but only with the engine off.
The problem is only with the engine running. Regardless of the SW positions, the step will not extend when opening the door with the engine running. [which is annoying is I need to step back out after startup. Pretty much all the time as I'm doing my final readiness walk around while letting the engine warm-up and air pressures to stabilize, etc.]
Link to the older thread below for reference.
When I figure this out, I'll return and post the solution.
